Task-Oriented Conversation Generation Using Heterogeneous Memory Networks

How to incorporate external knowledge into a neural dialogue model is critically important for dialogue systems to behave like real humans. To handle this problem, memory networks are usually a great choice and a promising way. However, existing memory networks do not perform well when leveraging heterogeneous information from different sources. In this paper, we propose a novel and versatile external memory networks called Heterogeneous Memory Networks (HMNs), to simultaneously utilize user utterances, dialogue history and background knowledge tuples. In our method, historical sequential dialogues are encoded and stored into the context-aware memory enhanced by gating mechanism while grounding knowledge tuples are encoded and stored into the context-free memory. During decoding, the decoder augmented with HMNs recurrently selects each word in one response utterance from these two memories and a general vocabulary. Experimental results on multiple real-world datasets show that HMNs significantly outperform the state-of-the-art data-driven task-oriented dialogue models in most domains.Comment: Accepted as a long paper at EMNLP-IJCNLP 201

An insight into the mechanism and evolution of shale reservoir characteristics with over-high maturity

AbstractOver-high maturity is one of the most vital characteristics of marine organic-rich shale reservoirs from the Lower Paleozoic in the south part of China. The organic matter (OM) in shale gas reservoirs almost went through the entire thermal evolution. During this wide span, a great amount of hydrocarbon was available and numerous pores were observed within the OM including kerogen and solid bitumen/pyrobitumen. These nanopores in solid bitumen/pyrobitumen can be identified using SEM. The imaging can be dissected and understood better based on the sequence of diagenesis and hydrocarbon charge with the shape of OM and pores. In terms of the maturity process showed by the various typical cases, the main effects of the relationship between the reservoir porosity and organic carbon abundance are interpreted as follows: the change and mechanism of reservoirs properties due to thermal evolution are explored, such as gas carbon isotope from partial to complete rollover zone, wettability alteration from water-wet to oil-wet and then water-wet pore surface again, electrical resistivity reversal from the increasing to decreasing stage, and nonlinearity fluctuation of rock elasticity anisotropy. These indicate a possible evolution pathway for shale gas reservoirs from the Lower Paleozoic in the southern China, as well as the general transformation processes between different shale reservoirs in thermal stages

Transformation of Chinese OEM-----Case study

Due to the globalization trend, the transformation of Chinese OEM has become a hot topic in the last decades. Although the previous literature suggested that there were many different determinants influencing firms to be successful companies, there is a lack of combination in the context of Chinese OEM. Thus, the purpose of this research study is to find out the approach of Chinese OEMs to successfully launch their own products based on three perspectives - organizational structure, processes and culture.Applying a qualitative approach, the data was gathered through semi-structured telephone interviews with the senior personnel of one Chinese OEM company (Damekiss), complemented with secondary data collected from the company’s and public websites.The results of analysis showed different views of how organizational structure, process and culture influencing on the transformation of Chinese OEM. We found that four functions (i.e. manufacturing, distribution, new product development and human resource management) influenced the transformation of Chinese OEM in organizational structure perspective. Among these functions, human resource management and distribution are extremely weak in the organizational structure of Chinese OEM. Regarding to the process of formulating these functions, the deep understanding of the customers’ preferences and collaboration partners that influenced building distribution were figured out. In the case company, it showed a relative poor ability on distribution which would be the barriers for further developing. Building HRM process was raised as another issue of the transformation of Chinese OEMs. According to the case company, HRM was poorly organized. The recruitment did not get enough attention; the training programs stayed at a lower level. The last not least, the corporate culture was also proven to be playing an important role in the transformation of Chinese OEMs. Awareness of corporate culture as one of significant aspects influencing the entire company was found in the case company. Slogan, company heroes and rituals as an internal culture were properly used to motivate employees

The influences of national culture on new product development collaboration

To  ensure  success  in  the  rapid  pace  of  globalization,  it  is  crucial  for  companies  to understand the management practice within and outside national boundaries. This study investigates  the  influences  of  national  culture  on  new  product  development  (NPD) collaboration between China and Sweden.   By applying  the  qualitative approach  with a single  case,  the  study  shows that national culture influences on NPD  collaboration  by  means  of organizational  culture and  work values   regarding   six   national   culture   dimensions   between   China   and   Sweden. Concerning  organizational  culture,  power  distance  and  masculinity  versus  femininity dimensions  of  national  culture  have  impacts  on  NPD  collaboration.  In  terms  of  work values, the  influences  of power  distance and uncertainty avoidance are  ranked at  first place, whereas individualism and collectivism, masculinity  versus femininity, harmony and long-term versus short-term orientation are relative weak comparing with first two dimensions.   However,  the  results  also  show  that  some  organizational  characteristics  including uncertainty  avoidance,  long-term  versus  short-term  orientation  and  harmony  have barely  effects on NPD  collaboration. This  implies that there  could  be  context-specific factors  that  affect  performances  of  NDP  collaboration  regardless  of  in  which  country the NPD project takes place
